Skill: NFT portfolio

Bundled execution of the NFT portfolio workflow — NFT + wallet snapshot: NFT holdings, native balance, and ETH price for a given address in one call. One x402 payment runs 3 underlying tools (nft-holdings, wallet-balance, crypto-price); partial-success per step.

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/skill/nft-portfolio", {
